Tantalum

Rare, pure, and strong, tantalum is dense, shatterproof and extremely malleable—characteristics that set it apart from other contemporary metals.
In its natural state, tantalum is beautiful grey with a bluish tint, but a special patent pending ceramic glaze is applied to it when used as jewellery
to give the metal a matte black look and enhance its scratch-resistance. Tantalum is an inert metal, which means that it does not react to most
chemicals and does not dissolve in acid. It is also hypoallergenic and heat-resistant and is widely used in surgical and dental equipment.

Care and Polishing
To clean tantalum jewellery, use a solution of warm water and detergent-free soap with a soft cloth. When not worn, store your tantalum pieces in soft
cloth bags or the original box to protect them from the elements of daily exposure. Tantalum does not tarnish, and while scratch-resistant, may develop
a natural wear pattern over time.
